Android Studio Instant Run restart application always

Question

In Android Studio, the "Instant Run" function "Apply changes" restart application always, even if no change in code (Android Studio 2.3.0 - MacOS 10.12.3). This happen when application is in Debug and paused on a break point, if then I try to apply change the app restart

This is my build.gradle:

apply plugin: 'com.android.application'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}
buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
    }
}
allprojects {
    repositories {
        mavenCentral()
    }
}


android {
    compileSdkVersion 23
    buildToolsVersion '25.0.2'
    dexOptions {
        javaMaxHeapSize "4g"
    }
    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 23
        multiDexEnabled true
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }



    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src/main/java']
            resources.srcDirs = ['src/main/java']
            aidl.srcDirs = ['src/main/java']
            renderscript.srcDirs = ['src/main/java']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        //instrumentTest.setRoot('tests')
    }
}

Instant Run is always disabled in the debugger:

On Android Studio 2.3, if you deploy your app by clicking Debug , pushing subsequent code changes by clicking Apply Changes always results in a cold swap. To learn more, go to issue #234401.

From https://developer.android.com/studio/run/index.html#instant-run

Other than that, your configuration seems to check all the boxes.
